Hello,

I have a Sandisk SRRD73 CF/SD card reader and I am not able to use it
with linux. I'm using Debian unstable on an Athlon XP1600. I tried with
kernel 2.4.20 and 2.4.21pre4. When I plug the reader, cards are detected
correctly (a 128Mb CF and a 32Mb SD) but once I tried to mount or fdisk
there is many errors.

Cards are correct (I read them on my Zaurus), and reader should be
supported (http://www.qbik.ch/usb/devices/showdev.php?id=1463) so I
don't have any idea of what to try more.

Here are the logs:
